It’s better to prefer DU regular colleges given the choice. Course-wise, choosing B.Com over BBA is better, unless you are particularly interested in doing BBA. Here are some of the reasons why you should choose DU for your degree.

• Other colleges charge reasonably higher tuition fees compared to DU, especially for courses like BBA.
• If you are taking admission to a regular DU college try to engage in different activities. Join societies, clubs, etc. It will help you in the long run.
• In DU colleges, you will get enough time to do internships for work experiences. This will definitely look better on your CV.
• If you are a graduate from DU, then you will get certain advantages over Non-DU candidates, in job interviews.
• If you want to study CA, CS, etc. along with your degree, then it is better to do a B.Com. Since the B.Com syllabus will have more subjects related to CA, CS, CWA, etc. You can also easily prepare for other competitive exams, without your college timing being an issue. 

Considering all these factors, doing B.Com from a regular DU college will be better than doing BBA from Amity University. 

Ramanujan is better than Deshbandhu in every aspect. They offer the best faculty and infrastructure.

• Ramanujan college was previously Deshbandhu evening college but now it has transitioned to a morning college.
• Both the colleges are next to each other with separate buildings.
• Ramanujan definitely has much better infrastructure, faculty and student crowd than Deshbandhu college.
• If you want to pursue B.Com, Ramanujan will be a better option as it is the third largest college for commerce education under Delhi University.
• Ramanujan has a few good societies where students can participate.
• The commerce society of Ramanujan is the best in the college.
• The placement situation is more or less the same in both the colleges.

The downside to Deshbandhu is the environment. It has a very political environment with frequent conflicts happening every time during university elections. Therefore for focussing mainly on your studies you could go for Ramanujan.

Among the colleges mentioned above, Maitreyi College is the best option for pursuing a B.Com degree. However, it is a girl's college. The infrastructure of the college is quite good. The campus offers a decent learning environment. The area surrounding Maitrayi is neat and clean with many embassies. 

Motilal Nehru is a morning college whereas Shaheed Bhagat Singh College (SBSC) has both morning and evening colleges.

At first, you will have to decide your preference for the timings. One of my friends graduated from Motilal Nehru College (Day) and has had flatmates studying in evening colleges. According to him their routines were completely different. So, the choice completely depends on you and which time of the day you are comfortable with.

Motilal Nehru has a competent faculty, with spacious new buildings, library and good placements. They also have active societies such as Enactus, DebSoc, Archon Leadership Cell and others.

Another benefit of being in Motilal is that it is located in the South Campus and is always crowded. This crowd attracts the building of proper hangout places. Its Satya Niketan market offers good places to eat and good coaching centers.

On the other hand SBSC (E) would only give you the benefit because of its past reputation, good sports infrastructure and its proximity to Select City Walk.

Therefore make an informed decision as this will be motivated towards the shaping of your career.

For a B.Com, Ramjas will be the best option among these. It has an excellent commerce faculty. It offers a great academic atmosphere. Ramjas has many active clubs and societies that you can join. 

Ramjas College placements are pretty good for B.Com. According to the recent placement drive, the highest and average salary packages offered to students are respectively, INR 19.5 LPA and INR 5 LPA, respectively. Students get recruited as Risk Advisories, Audit Assistants, etc.
